SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 350,834, dated October12, 1886.

To all whom it may concern.-

Be it known that I, WILLIAM MoOoNNnLL, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Iniprovenient in Shutter-Fastenings,which improvement is fully set forth in the following specification andaccompanying drawings, in which k Figure 1 represents a top or plan viewof the portion of a shutter-fastener embodying my invention. Fig. 2represents a perspective view thereof on a reduced scale, showing theoperation of the fastener.

Similar letters of reference indicate corresponding parts in the twofigures.

My invention relates to an improvement in the turn-buckle or catch shownin the Letters Patent of the United States No. 343. 333, granted to meon the 8th day of June, 1886; and the invention consists in forming saidcatch with a shoulder on each side, so that the fastener will beunfailingly engaged with the catch, as-

will be hereinafter fully set forth.

Referring to the drawings,'A represents a shutter of usual construction.

Brepresen ts the fastener shown in the Letters Patent aforesaidconsisting of a bar with a hook, O, at its end and laterally-projertingwings D near said end, the bar being hung to the inside of the shutter,so as to freely depend therefrom.

E represents a turn-buckle or catch, the same consisting of a bar havingits rear end pointed and formed near said end with a shoulder, E,whereby it may be driven into the wall of the building. The front end ofthe Application filed September 9, 1886. Serial No. 213,100.

bar carries a head, F, which is pointed of the form of a spear-head,leaving at opposite sides of the back of said head the shoulders G G.

In opening the shutter the hook O strikes the inclined side of the noseof the catch and rides on the same until it reaches the shoulder G, whenit drops behind said shoulder, as

shown in Fig. 2, thus locking the fastener tothe catch, and consequentlyreliably holding the shutter in open position.

Should the shutter be opened forcibly, the catch flies laterally, owingto its centrifugal action, and as it returns against the shutter itstrikes the opposite side of the nose of the catch and rides thereonuntil it reaches the shoulder G, when it drops behind said shoulder,thus locking the fastener to the catch and reliably holding the shutterin open position, this action not being possible in the catch shown inthe Letters Patent referred to, as the location of the hook on the sideof the catch opposite to the shoulder F leaves it disengaged from saidcatch, so that the shutter may be blown closed or left to rattle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A shutter-fastener consisting of a depending bar freely secured to theshutter and a catch formed of a bar having a pointed head with shouldersG G on opposite sides of the back thereof, substantially as described.
